An Evaluation of Risk Factors for Patient "No Shows" at an Urban Joint Arthroplasty Clinic.

Background: Patient physical health and provider financial health are both affected when patients are unable to attend scheduled clinic appointments. The purpose of this study is to identify risk factors for patients missing appointments to better target interventions to improve appointment attendance.

Methods: We reviewed scheduled arthroplasty appointments at an urban academic orthopaedic clinic over a 3-year period.

Factors Determining Home Versus Rehabilitation Discharge Following Primary Total Joint Arthroplasty for Patients Who Live Alone.

Patients who are discharged home following primary hip and knee arthroplasty have lower associated costs and better outcomes than patients who are discharged to skilled nursing facilities (SNFs). However, patients who live alone are more likely to be discharged to an SNF. We studied the factors that determine the discharge destination for patients who live alone after total joint arthroplasty (TJA) at an urban tertiary care academic hospital between April 2016 and April 2017.

Off the Market: The Percentage of Products Available After Ten Years.

Background: We observed that medical devices advertised in journals are often no longer available 5 to 10 years after first being advertised. In this study, we quantified the percentage of products advertised from 2003 to 2008 in the which were still available 5 to 10 years after first being advertised.

Methods: We created a database of 427 unique orthopaedic products advertised in the .

The 22-Modifier in Reimbursement for Orthopedic Procedures: Hip Arthroplasty and Obesity Are Worth the Effort.

Background: Orthopedic surgeons utilize the 22-modifier when billing for complex procedures under the American Medical Association's Current Procedural Terminology (CPT) for reasons such as excessive blood loss, anatomic abnormality, and morbid obesity, cases that would ideally be reimbursed at a higher rate to compensate for additional physician work and time. We investigated how the 22-modifier affects physician reimbursement in knee and hip arthroplasty.

Methods: We queried hospital billing data from 2009 to 2016, identifying all cases performed at our urban tertiary care orthopedic center for knee arthroplasty (CPT codes 27438, 27447, 27487, and 27488) and hip arthroplasty (CPT codes 27130, 27132, 27134, 27236).

National Trends in Primary Total Hip Arthroplasty in Extremely Young Patients: A Focus on Bearing Surface Usage From 2009 to 2012.

Background: The ideal bearing surface for primary total hip arthroplasty (THA) in young patients remains a debate. Data on recent national trends are lacking. The purpose of this study is to provide an analysis on the national epidemiologic trends of bearing surface usage in patients aged ≤30 years undergoing THA from 2009 through 2012.

Total Joint Arthroplasty in Patients Taking Methadone or Buprenorphine/Naloxone Preoperatively for Prior Heroin Addiction: A Prospective Matched Cohort Study.

Background: Preoperative narcotic use has been associated with poor outcomes after total joint arthroplasty (TJA). The purpose of this study is to compare clinical outcomes of patients undergoing elective TJA while concurrently being treated with methadone or buprenorphine/naloxone for prior heroin addiction to a matched control group.

Methods: From an electronic medical record, we collected age, gender, body mass index, the presence of back pain, smoking status, history of alcohol abuse, preoperative use of a pain clinic, and use of antipsychotics, antidepressants, or systemic corticosteroids.
